ATTORNEYfl Patented June 11, 1940 UNlTED STATES PATENT ()FFiCE 1 Claim.

This invention relates to a sash drain, particularly intended for use upon screen sash.

It is the primary object of the invention to provide a novel and simple metal fitting easily applicable to any sash to drain outwardly therethrough water accumulating on the window sill between the window sash and the sash in which the drain is provided. With particular reference to screen sash, through which rain is apt to drive, it is a further object to release accumulations of water without admitting insects through the sash.

It is a further object of the invention to provide a unitary metal fitting applicable to a sash for the purposes stated, and provided with a trap door for the release of water and the exclusion of insects, and means for unitarily holding such trap door in a position where its functioning will be automatic.

In the drawing:

Fig.1 is a view in perspective showing a fragment. of a screen sash, a window frame, and sill, the screen sash being equipped in accord-- ance with this invention.

Fig. 2 is a fragmentary detail view in transverse section through a screen sash and sill showing on a. larger scale a cross sectional view of the device embodying this invention.

Fig. 3 is a front elevation of the parts shown in Fig. 2.

Fig. 4 is a view principally in perspective and partly broken away, showing the metal fitting employed.

Like parts are identified by the same reference characters throughout'the several views.

The screen sash 5 is fitted to the window casing 6 and sill l in the usual way. The lower rail of the screen sash isprovided with a notch at 8 into which I introduce my improved. fitting.

The fitting comprises a face plate 9 apertured to receive the mounting screws l0. Formed integrally with the face plate is a box-like housing I 5 which extends intothe notch 8 ofthe sash and provides at It integral supports for a pintle ll engaged by the ear E8 of the trap door 26.

At its lower margin the trap door curves outwardly at 2!, and its length is such that it rests on the sill at an angle as shown in Fig. 2. From the position there illustrated, the door can be opened in an outward direction only, and it is so small and light that any accumulation of water behind it will readily force it open, thus allowing the water to drainfreely out through the sash- It will be observed, however, that when the trap door 20 is opened it will tend to be restored by gravity automatically to the position illustrated in Fig. 2, thereby closing to pro vent the ingress of insects after the water has escaped.

During the application of the sash to the window the automatic trap door 20 might easily become reversed as to its angle of inclination if it were not for the provision on the housing I5 of one or more ears 22 which are positioned behind the trap door and maintain it in its out:- wardly inclined position against any possibility of inward displacement.

I claim:

A device of thecharacter described, comprising a fitting unitarily applicable to a notched sash and comprising a downwardly notched face plate, a housing open at its bottom and comprising a top and. sides projecting inwardly from said face plate, a trap door disposed at an outward inclination within the housing, and means providing a pivotal connection between the trap door and the housing adjacent the upper edge portion thereof, from which connection the trap door extends outwardly and downwardly, said housing comprising means supporting the trap door against reversal of its angle of inclination.
